. The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be understood from an illustrative, rather than a restrictive standpoint.

The inventive idea involved is capable of receiving a variety o-f mechanical expressions, one of which, for the purpose of illustration, is shown in the accompanying drawings, in which- Fig. 1 is a side view partly in section of my improved lather mixer;

Fig. 2 is a sectional view taken on line 2--2 Fig. 1;

Fig. 3 is a fragmental sectional view taken on line 3-3 Fig. l; and

Fig. 4 is a diagrammatic view of the electrical connections.

Referring now to the drawings in detail 5 indicates a base upon which is mounted an electric motor 6 having a shaft 1 upon which there isfsecured a clutch member 8 in mesh with a second clutch member 9 carried on a shaft I0 which extends into a mixing chamber II and which shaft carries a mixer or churner I2.

Directly above the mixing chamber II and in 5` communication therewith through a valve opening.- I3 is a liquid soap container I4 The opening I3 is normally closed by avalve disk or plug I5-from which extends aL stem I6 pivotally secured to one end of alever I1 pivoted at I8. 10 Pivotally secured tothe opposite end of the lever I41 is a link I9 the lower end of whichr-issecured to a lever arm pivoted at 2I, rthe lsaid pivot 2| also passing through a bracketr 22` secured to thebase 5. Y o

Thelever arm 2D is normally maintained in itsl upperuposition by means ofk a plunger 23 which isV pressed upwardly by a coiled spring 24. The 'said plungergmay operate in a cylinder 25 which maybe provided with a' slot 26 to ac- 2&0 commodate a pin 21 extending fromthe plunger 23.y A wirej30 extending from oneside of the motor 5 Ais-,electrically connected toma-,terminal 3'Ithe'other side of the motor being vconnected by a lead' wire 32'to one leg 3'3of an electric 25 plug (seeFig. 4), the second leg 34 of which is connected bya lead wirei to a terminal 36. When the plug is connected toa source ofi-electric supplygand the 4leverarm is inyits normal upwardr position vthe circuit is broken. However, 30 upon thevdepression of the, said lever arm to open oruriseatthevalve I5 to permit the-flow of liquid soap into the mixing' chamber I I, contact points 31 and 3 8i-wi11engagvegthe terminals 3l and 36 to close the electric .circuit to run the 35 motor 6 and rotate the mixer I2 to make lather in the chamber I I which will be delivered to the barbers hand through a nozzle 40 leading outwardly from the said chamber. It will be seen that the hand which depresses the lever arm 20 o may receive the lather so that only one hand need be used to operate the device and to receive the lather.

The shaft section 20 which carries the mixing wheel I2 is surrounded by suitable packing ma- 45 terial 4I and by gaskets 42 and 43 to make the device leak-proof. The said packing material may be kept in place about the shaft by means of ttings 44, and 46. The entire device is surrounded by an outer casing 41 which at the 50 top thereof is provided with a hinged cover or lid 48 which when open will permit of access to the liquid soap container I4. If desirable an electric lamp 49 may be provided to keep the liquid soap in a slightly heated condition.

as new and desire to secure by Letters Patent ist' f 1. A device for producing lather from liquid soap comprising a liquid soap container, a mixV` ing chamber in communication therewith, a'v

valve interposed between the container and the mixing chamber, a mixer in' the mixing-cham ber, a pair of electric terminals, a motor` or-op7` erating thefrnixer normally in open circuit with theterminals, a lever pivotally mounted fr'ver-v tical swinging movement at one side of the I nix-I ing chamber and' constituting means for bridge ing the terminals, spring means for normally holding the lever out of bridging engagement with the terminals, a rocker bar for actuating said valve pivotally carriedby' said container,

and a link connecting said rocker bar with saidl lever for accomplishing opening ofthe valve when the lever is moved into bridging engagement with the electric terminals.

2. A device for producing `lather from liquid' soap'comprising a base, a mixing chamber rising from said base, a container for liquidfsoap `over said mixing chamber having an outlet at its bottom for delivering soap into the mixing chamber, a valve for controlling iiowof soap through the outlet having a stern extending ver-v tically in the container, a rocker bar pivotally mounted and extending horizontally through' the peripheral wall of the container with its inner" end connected with the upperend'of the valve stem; a mixerin themixing chamber, a pair of' electric terminals, a motorA for operating thev mixer normally in open circuit with thel terminals, a bearing bracket carried by said base;l a lever pivotally carried by said vbearing bracket'Y and extending horizontally over the terminals and yieldably held outof bridging engagement therewith, and a link connecting said lever with' the outer end of saidl rocker bar to tilt" the rocker' bar and move the valve to an opened-position" when the lever is depressed forbridging engage-- ment with the electric terminals.

3. A device for producing lather from liquid soap comprising a base, a mixing chamber carried by said base, a container for liquid soap over said mixing chamber having an outlet at its bottom for delivering soap into the chamber, a pair of electric terminals carried by said base, a mixer in the mixing chamber, a motor for operating the mixer normally in open circuit with-the terminals, a valve for controlling flow of soap through" theoutl'et"havingfaf'steni extending verticallyin the container; arockerlbar'pivotally mounted and passing through the peripheral wall of the container with its inner end connected with the valve stem to open the valve When"'the rocker bar is tilted in one direction, a lever pivotally mounted and extending horizontally over the electric terminals for bridgin'gf theiterminals" when the lever is depressed, springfmeans carried by the base under the lever for normally holding the lever out of bridgingi engagement'wltli the"te'rminals,` and a= link connecting said lever' with the' outer vendof :the rocker' bar;
